Since there are impatient members,here is what I suggest about
releasing the CCL route.
1st release:CC16 Marymount → CC12 Bartley(Or
the other way)
2nd release:Circle Line Discovery
3rd release:CC1 Dhoby Ghaut → CC16
Marymount(Or the other way)
4th release:CC1 Dhoby Ghaut → CC29 Harbourfront(Or
the other way)
Hope this helps!
It's stated in the first post that
1st release: Dhoby Ghaut --> Paya Lebar
2nd release: Dhoby Ghaut --> Marymount
3rd release: Dhoby Ghaut --> Harbourfront
4th release: CCLE? (Promenade --> Marina Bay?)
